FileExplorer

Hi,

since there is absolutely no documentation about RadFileExplorer I have to ask the question here.

First of all - NO documentation means really NO.
I'm used from Silverlight that some controls are not describe in the "Controls" section of the help.
But at least there is help (even tho it is just "automatically generated content" in the class references).
But here I find nothing at all.

Anyhow - from the properties I found an event

OnItemCommand

But it seems as if this event is never fired.
My approach is to give the user a browser - after he selects a file I decide if this file should be downloaded, edited with a RadEditor or...

The Idea was - I handle the OnItemCommand.
And I guessed there is a "CommandName==Open" or something like this.
So the idea was:
....OnItemCommand(....) {
if(e.CommandName=="Open")    {
    if(IsFileEditable(e.Path))    {
      string strContent=ReadFile(e.Path);
      RadEditor1.Content=strContent.
      RadFileExplorer1.Visible=false;
      RadEditor1.Visible=true;
      SaveButton.Visible=true;
      CancelButton.Visible=true;
}
.....
BUT - the OnItemCommand handler never get's fired - and due to the missing documentation I have no idea how to solve this.

And YES I have seen the "FileExplorer" sample.
BUT: the things get handled on the client - I need them on the server.
AND: exactly the thing where the FileExplorer comes to play is not visible since this is done in some other APSX file - and this file is not listed in the sample.
So all I could see there was a pages which calls a dialog and from this it get's (with some kind of magic :)) the filepath.

Regards

Manfred

Hi,

I tried to build a workaroung - but I got stuck.
The approach was the same as before - then I got the problems and reduced the things to do as less as possible.
First the idea - I use RadManager - call a function.
In this function I switch the UI (hide FileExplorer, show Editor and Save / Cancel buttons).
Reduced I do nothing more than call the function and simply return.
The Error occures as soon as I include the FileExplorer in the updated Controls.
This is a must - since I plan to hide / show the thing.
Currently I simply set a label to the path and return.
Here my ASPX

    
                <script type="text/javascript">  
        
                    function OnFileOpen(sender, args) {  
        
                        var item = args.get_item();  
        
                        if (item.get_type() == Telerik.Web.UI.FileExplorerItemType.File) {  
        
                            args.set_cancel(true);  
        
                            InitiateAsyncRequest(item.get_path());  
        
                        }  
        
                    }  
        
                    function InitiateAsyncRequest(argument) {  
        
                        var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");  
        
                        ajaxManager.ajaxRequest(argument);  
        
                    }  
        
                </script> 
        
            </asp:Content> 
        
            <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">  
        
                <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="alpPan1" OnAjaxRequest="RadAjaxManager1_AjaxRequest">  
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">  
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="lblErg" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="rfxFiles" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
                </telerik:RadAjaxManager> 
        
                <telerik:RadAjaxLoadingPanel ID="alpPan1" runat="server" Height="75px" Width="75px" Transparency="5">  
        
                    <img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>' style="border: 0;" /> 
        
                </telerik:RadAjaxLoadingPanel> 
        
                <telerik:RadFileExplorer ID="rfxFiles" runat="server" Configuration-ViewPaths="~/XFiles" OnClientFileOpen="OnFileOpen">  
        
                    <Configuration ViewPaths="~/XFiles" SearchPatterns="*.*"></Configuration> 
        
                </telerik:RadFileExplorer> 
        
                <telerik:RadEditor ToolsFile="/Images/ToolsForContent.xml" Skin="Office2007" Language="de-DE" ID="edTheDefault" runat="server" Width="600px" AutoResizeHeight="true" Visible="false">  
        
                    <Content> 
        
                    </Content> 
        
                </telerik:RadEditor> 
        
                <asp:Label ID="lblErg" runat="server" /><br /> 
        
                <asp:Button ID="btnSave" runat="server" Text="Speichern" OnClick="btnSave_Click" Visible="false" />&nbsp;&nbsp;  
        
                <asp:Button ID="btnCancel" runat="server" Text="Abbrechen" OnClick="btnCancel_Click" Visible="false" /> 
        
            </asp:Content>

And my Code behind:

    
                protected void RadAjaxManager1_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e) {  
        
                        lblErg.Text = e.Argument;  
        
                        return;  
        
                            }

The label displays the path - but the Filemanager shows the loading symbol and does not stop until I select (about 3 to 5 times) a different directory.

Hi Manfred,

First I would like to apologize for the missing documentation. The RadFileExplorer control provides one server side event - OnItemCommand, which is called on the following commands:

UploadFile - fired before each uploaded file is saved
MoveDirectory - fired before a directory is moved/renamed
CreateDirectory - fired before the file explorer creates a new folder
DeleteDirectory - fired before the file explorer deletes a folder
DeleteFile - fired before a file is deleted
MoveFile - fired before a file is moved/renamed

Unfortunately, the fileOpen command is fired only on the client. If you want to do some server-side processing when the user tries to open a file, you need to handle the client open event (OnClientFileOpen) and make an postback or ajax request there with the selected file name.

I can see that you already have taken the correct approach. Unfortunately, I was not able to reproduce the problem using the code you sent and the current RadControls release (2009.1.402 .NET 2.0). If possible open a formal support ticket and send us a page or a sample project we can use to reproduce it.

Best wishes,
